Iīm about to build a 12" WO using two 12" Rockford Fosgate RFR3112.Powered by a Digital Designs Z1.Iīm only going to raise it up from 12" to 14" on the design.Iīve read somewhere that Steve had recommended to do so.I will build the 36" x 36" version..and the height 14". Anyone who think this would work? Or not??Give me some positive answers.. :) Perhaps this subject has been discussed over and over but the use of the RF woofers are quite rare i would think.

From what I have seen they should put out some very loud, low bass in the WO. The only major worry I would have is depth for mounting. When you slant the board to accommodate the cone, make sure the magnet will clear before you get too deep into construction.

Nope.. havenīt bulit it yet.. Just drawn the lines..Like you said.. I just might cut a hole in the side and put a plateover it, it just might work! Iīll try some modifications tomorrow.. Itīs 8:25 PM here right now

i agree with you, find out where the magnet will touch, cut a hole big enuf to allow for the magnet and then useing mdf rings and mdf circles, seal the hole from the outside. building it the way you stated (14 tall and 36x36) is the best way i believe.

but i might try the scale every number by 1.2 one day?

let us know how it works out please.

edit; if its only .25" off, you can sand that out with a grinder pretty easy, no need for any mods to the box. if you use 3/4 mdf -.25" your wall will still be 1/2" thick a lil fiber glass or epoxy and im positive it will be problem free for life.

Guess what? THEY FIT!! Ok ok.. some modifications were maid.I now call this WO "Battle of the bulge" :DWill put up som pics of it when I have my camera with me.Looks kinda wierd, but who cares.. as long as it rocks.

I actually built the WO with 12" subs before.. That time I scaled it up by 1.2And it... SUCKED! Scaling is imho a big no no. Thatīs why iīm bulidingafter the original this time. Only raising it up 2".

Didnīt matter in my case.. The magnets are 300oz.In the original plans of the WO the space on the baffle is to small for a 12" without slanting the baffle.And I also use double baffle. Took me 2 hours tryingto fit them without modification. There was no way in hellto fit them without changing the apperance of the box.The RF woofer has a mounting depth of 7" and the magnetis 8.34" wide and about 4.3" thick. Now there is about 0.59" between the magnet and the outer wall.Well iīm going to take some pics of it during the build.

very interesting, can you tell us more about the subs and amps you used and what about the sound was it (punchy peaky, gutless weak no lows no highs ?? etc etc) that sucked? im very supprised such a small deviation from the origional was so dissapointing, and i am seriously thinking about building it scaled by 1.2 so any thing you can offer about your experience i would appreciate.

I ran into the same problem with 12" in a WO.What I did was to route a hole in the side of the WO to accomidate the driver and I added a larger than needed patch to the outside of the cabinet.If I was going to build another I'd use plywood instead of MDF to reduce weight.I've built tree WO's and this onr hits hard and low.I was comparing it to my imperial ( set up as sub)and it hits as hard in the lower area's but was a little muddier in quality.All in all a great sub for it's size.

Yeah, well perhaps i could have routed a hole i the cabinet butI did it the hard way by drawing a kind of lump on the outside next to the baffel. Now the subs can be mounted straight.Well the bulid has been kind of slow since I installedthe amp in my car with my old box. A bandpass box..Holy moly it hits sooo hard you wont believe. BUT!the bulid must go on.. (sounds almost like a queen song?) Well well I will update again when progress has been made.

just curious, what are the mounting depth of the some 12's that have fit in the WO? Do most just increase the height of the box to accomodate, or scale the whole box up? I've got a customer that would be a perfect for a 12" WO--he's got Memphis M3 12's with a mounting depth of 6.1 inches-wondering if they are worth the build time/wood

Well, the Rockford in question from this thread has a mounting depth of just over 7" and needed mods to fit. I think 6" will go pretty close and anything under that should work without any mods. Seems like the ones that I remember from the past had close to 6" mounting depths.
